how to get out of The Isis temple ?

ciao a tutti,
is there a way to come out of the Isis temple without speaking with Kerah & resurrection of An.... ?
I killed the guardian of Isis (it's a dragon and i dit it, but reluctantly) and the darkened too (brings a lot of ex-points).
If i try to leave the temple on the point of entering, there is a wide gap and a silly button, but i couln'd find a way out.
I have to go back to the Brimloch port to heal my party members (insane), to take several day of relaxation and make good money with my goods & items from the enchanted island.

I'll mail you any amount of any curency, but please help me.

Yes, you can go back out sort of the way you came in -
In the room with all the spikes that come down to crush you and the pit on the far side between you and the exit there is a button - run over to the button missing as many of the spikes as possible and push the button. This places your characters on the far side of the pit - then all you need to do is look for the lever on the end wall which was the same lever you switched to enter this dungeon and you're out!

Good luck!
